Tissue and organs from which livestock animal are used in human surgeries?

The use of tissue and organs from pigs in human surgeries is well-established, making pigs a critical source in the field of xenotransplantation and medical research. Pigs are often chosen for this purpose due to their anatomical and physiological similarities to humans, which enhance the likelihood of successful grafting and integration of tissues.

Pork heart valves are frequently used as a substitute for damaged human heart valves, and skin from pigs is utilized for burn victims because it has similar properties to human skin. Furthermore, the organs of pigs, like kidneys and livers, are studied for transplantation purposes. The advancements in genetic engineering have also expanded the possibilities of using porcine organs for human transplants, addressing the shortage of human donors.

While cows, sheep, and chickens have their own applications in medicine and food production, they are less commonly used in direct human surgical procedures involving tissue and organ transplantation. This makes pigs the appropriate choice in this context.
